Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
Prepare
Trim off the tough parts of the sweetbreads.
Scald the sweetbreads in a pot of water with a little coarse sea salt for a few minutes.

Coat the sweetbreads with the beaten egg.
Sprinkle bread crumbs over the sweetbreads.
Drizzle with clarified butter.
Add more bread crumbs.
Roast the sweetbreads for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; the dish is built around cooking them until tender and crisp outside.
- Fine bread crumbs
- Form a crisp, browned crust on the outside as they roast.
- Clarified butter
- Carries heat and helps the crumbs brown evenly without burning as quickly as whole butter.
- Beaten egg
- Acts as a glue so the bread crumbs stick to the sweetbreads.
- Browned flour
- Thickens the gravy and adds a toasted, nutty flavour.
The step that matters
Roast the sweetbreads for 15 minutes. Egg and crumb coating must be set and evenly golden before the gravy is added; too little heat leaves the crust pale and soggy, while too much browns the crumbs before the sweetbreads are cooked through.

- Figfits about as well
- Raisinfits about as well
- Plumfits less well
Fit is the average pairing score against egg, bread, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
